.motor vehicle-and 2 indicates la detachable lextension ofsaid casing Whichis provided with perforations 3 and which isheld: to.A the casi-ng bythe/latches An insulatedtank 5 -i s.place.d in the CaSlllg', .said-taii.k'liaviiig double YWalls@spaced apart to -i 'e ceive insulating material 6 so. that watergplacedz in-,the tank ywill. not v freeze and will retain its heat lforfa 'long time. )A three-Waywalve encock l7 is-conneoted .with the lower part ofthe ta-nkby l the connection 8 and with -the npfperpart thereoffbythe connection 9 and a pipe 'lO .connects the third .nipple :of fthe valve with a three-Way `coc-k or valve ll placed, atgtheflowest point of: the up-take 12 y of the `cooling system. of the V motor of the vehicle. Tliegpart'of-the pipe lOlClllCent the cook 7 :is `formed With-the coilsffland these coils, fthe-.cock 7 land, its connections with the v. tank garegall located in the extensiQlr Zof the` casingil. Asheater. i;iasing- 1,4 is

placed in the extension and surrounds the coils 13 and this heater casing is connected With the exhaust manifold o't the motor by the pipes 15 which contain the valve 16 and the outlet of the heater casing is connected With the discharge pipe 17 so that by opening the valve 16 some of the exhaust gases will pass through the heater casing 14 and heat the Water passing through the coils 13. This valve can be controlled from the instrument board through the rod 18, and the valves 'i' and 11 are connected by the rods 19 With arock shaft 20 which is connected by a link 21 With a bell crank lever 22 which is pivoted to a bracket 23 on the instrument board and which has its handle part 22 passing through a slot 24 iiormed in a dial 25 carried by the bracket and which contains indicia for indicating the various positions of the bell crank for moving the valves to their desired positions in order to control the How of Water to and from thetank.

In order t0 force the water from the cooling system into the tank and vice versa I provide a tubular plug 26 designed to be placed in a spark plug hole of a motor and which has its upper part threaded to receive a spark plug so that the device forms a i'iring chamber When the motor is operating. This plug has a port 27 therein which eX- tends through a nipple so that the plug can be connected by a pipe 28 with a cock 30, the handle of which is connected with one of the rods 19 so it will be operated from the bell crank 22. A pair of pipes 31 and 31 connect the cock 30 With a yoke-shaped pipe 32 which has its nipple 32 connected by a pipev 33 with the port 34 at the top of the tank. A check valve 35 is placed in the pipe 31 and a check valve 36 in the pipe 31. these valves acting in opposite directions so that When the cock connects the plug 26 With the pipe 31 some ot the pressure in the cylinder will pass into the tank above the water level thereof through pipe 31 and its connections and when the cook is turned to connect the pipe 31 with the plug 26 the suction created by the moving piston Will create a vacuum in the tank through the pipe 31 and its connection. It Will be seen that the valve 35 in pipe 31 Will prevent the suction oi the moving piston from affecting pipe 31 and the tank While the valve 36 will prevent pressure entering the pipe 31 and the tank. Thus the motor can be made to create pressure or a vacuum in the tank by the positioning ot' the` valve 30.

A cock 37 is arranged on the top of the tank and casing tor permitting air to pass into the tank When desired. This cock is controlled from the instrument board through means of the rod 38. A tubular member 39 is connected With the top of the tank and passes through the instrument board where it is provided with a dial 40 and a thermometer 41, a linger 42 cooperating With the dial and being operated irom a float 43 in the tank through means or the connections 44 so that the level of Water in the tank can be ascertained and the temperature ot the Water will be indicated by the thermometer. The gauge will indicate when the tank is iull and the cooling system empty and the system full and the tank empty, as shown in Figure 9.

In order to enable the tank to be used as an auxiliary tank for gasoline in the summer time or when the device is not being used in connection with the cooling system7 I place a threaded nipple 45 in the bottom of the tank and casing and place therein a plug 4G for receiving a tube which may be connected with the carbureter or a tank ot the fuel system so that the auxiliary supply ot gasoline can be V,ted to the said system. A valve can be placed in the tube and operated from the rock shatt 2O by connecting one ot the rods 19 off said shait't with said valve. It will be seen that the dial 25 has the Word gas thereon or'indicating Where the handle 22 is to be located to open this valve -in the gas line. The plug 46 is substituted for a solid plug when the device is being used with the cooling system. plug 45 provides an opening for cleaning the tank.

In order to permit the valve 11 to be moved by the handle 22 to permit the Water to be drawn rom the cooling system to the tank by moving the handle 22 from the cti position on the dial to the drain position and to permit the Water to be forced by pressure .trom the tank to the sysn tem by moving the handle 22 from its eti position to its till position I provide said valve ivith the passages 11 Which communicate with the ports 11X so that the valve Will connect the pipe 10 With the up-take 12 when in either one ot its two positions. By Swinging the handle 22 to its loivermost position the valve 11 Will be opened to the drain 11 so that the cooling system and the tank will be drained.

From the foregoing it will be seen that by moving the handle 22 downwardly one point. the handle being held in its adjusted positions by the projections 2. on the bracket 23, and starting the motor a suction will be created in the tank and the valves 11 and 7 Will be moved to a position Where this suction Will draw the Wai er from the system into the tank. After all the Water has been drawn from the system, the gauge indicating this, the handle is moved to its oft position so as to close the cocks and the valve 30. Then the motor is stopped. The entire amount of Water in the cooling system will novv be inthe tank and as said tank is insulated the Water cannot freeze and as the rThe l freezing.

to enter the tank to replace-thef-Water leav- H ing the same and the bell .crank isfmoved to.y

- a point to open the valves 7 and 11 to permittheJ-Water tov fion/'from thel tank back into the system. If the Water has become cold the valve 16 can be opened and the motor started to heat the Water as it passes through the coils 13 by the exhaust gases iovving through the heater casing 14. I/Vhen the motor is operating the valve 37 should be closed and the valve 30 moved so that the engine will create pressure in the tank to force the Water therefrom. The valve 37 can be used to permit the Water to flow back into the cooling system from the tank under the action of gravity when the engine 1s not ruiming and it is not necessary to heat the Water. In this case the coils 13 act as a Siphon to empty the tank, the large coil being of less height than the level of the Water in the tank When all the Water is in the tank.

The heater arrangement can be also utilized for heating the car or vehicle.

By using this arrangement on automobiles and the like it is not necessary to use alcohol or other anti-freezing mixtures in the cooling Water though such mixtures can be used if desired. The tank, being insulated, Will prevent the Water from freezing so that after the vehicle has been used and is to be left for the night the handle is set to cause the motor to create a suction in the tank and the valve set to permit this suction to draw the Water from the system into the tank. Then the handle is put in its neutral position and the motor stopped. This Will leave the system empty. Then When the vehicle is to be used again the parts are set so that the Water Will pass from the tank to the cooling system under the action of gravity, or the parts may be set so thar, when the motor is started, pressure will occur in the tank and the valves opened to permit the water to flow back into the system from the tank, the Water being heated by the exhaust gases, When desired, by opening the valve 16. All the controlling means are arranged on the instrument board so that the driver can operate the apparatus Without ieaving his seat. As before stated, the tank can be used as an auxiliary tank for fuel when it is not being used for the Water cooling system.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the.

combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claims.
